KNOCKED UP star Katherine Heigl plans to get 'knocked up' for real this summer (08). The actress hopes to join the current swell of celebrity mums-to-be later this year. She says, "I want to start in, like, July." But her new husband, Josh Kelley, isn't quite as keen. Heigl adds, "He's saying the following July. I'm thinking maybe a compromise - sometime in December." The couple wed in Heigl's native Utah on 23 December (07).
